Possible iOS / iPhone bug? Suddenly get no sound at all from Duolingo.
I've never noticed this before but today the sound suddenly stopped working when I was learning German. I've tried resetting my phone, turning it on and off, re-installing the Duolingo app, playing around with the volume controls both with the mute button on and off and with putting earphones in and nada.
When I use the iphone music / iTunes however, it's fine and plays songs normally. I've checked that both the volume, ringer, and headphone levels are high enough but for some reason have stopped receiving all sound from Duolingo.
